Abstract
Describes InfoTrac (on laserdisc) and WILSONDISC (on CD-ROM), wich currently represent the only efforts to bring general periodical literature to end-users, and reports on the published reactions of librarians and users to these 2 products, as well as presenting a comparison of their search techniques and presentation of information to end-users. Reports from the field indicate that WILSONDISC is proving to be as popular with users as InfoTrac, and although the 2 systems provide different approaches to the presentation of general periodical citations, undergraduates appear able to adapt with little difficulty.
